10. Lena Headey - 300

When you talk about beauty and Game of Thrones it's often hard to bring Cersei Lannister up without thinking about something completely horrid she's done. Thank goodness that Lena Headey has been super attractive in more than just this show. In 300 she plays Queen Gorgo and is an equally tough woman, though without Cersei's less wholesome and disgusting habits... if you know what we mean.
